Computer Predicts Anti-Cancer Molecules
(June 17, 2008) — A new computer-based method of analyzing cellular activity has correctly predicted the anti-tumour activity of several molecules. Research published today in BioMed Central's open access journal, Molecular Cancer, describes 'CoMet' – a tool that studies the integrated machinery of the cell and predicts those components that will have an effect on cancer.

Magnets Capture Cancer Cells
(July 24, 2008) — Magnetic nanoparticles coated with a specialized targeting molecule were able to latch on to cancer cells in mice and drag them out of the body. The results are described in a study published online this month in the Journal of the American Chemical Society. The study's authors, researchers at Georgia Institute of Technology, hope that the new technique will one day provide a way to test for—and potentially even treat—metastatic ovarian cancer.

Bellamkonda's Research Highlighted in Science
(July 10, 2008) — Peripheral nerve regeneration across long nerve gaps is clinically challenging. Autografts, the standard of therapy, are limited by availability and other complications. Here, using rigorous anatomical and functional measures, we report that aligned polymer fiber-based constructs present topographical cues that facilitate the regeneration of peripheral nerves across long nerve gaps. Significantly, aligned but not randomly oriented fibers elicit regeneration, establishing that topographical cues can influence endogenous nerve repair mechanisms in the absence of exogenous growth promoting proteins. Axons regenerated across a 17 mm nerve gap, reinnervated muscles, and reformed neuromuscular junctions. Electrophysiological and behavioral analyses revealed that aligned but not randomly oriented constructs facilitated both sensory and motor nerve regeneration, significantly improved functional outcomes. Additionally, a quantitative comparison of DRG outgrowth in vitro and nerve regeneration in vivo on aligned and randomly oriented fiber films clearly demonstrated the significant role of sub-micron scale topographical cues in stimulating endogenous nerve repair mechanisms.

Non-invasive tracking of nanocarrier distribution in tumors
(July 3, 2008) — Nanocarrier-mediated chemotherapy has great promise in the treatment of cancer due to its ability to prolong the blood plasma half-life of the encapsulated chemotherapeutic and to selectively accumulate in tumors. However, in spite of important advances in the development of nano-chemotherapeutics, systemic chemotherapy is not the treatment of choice for malignant brain tumors, primarily due to the toxicity caused to non-tumor tissue. Therefore, novel techniques are required to understand and improve the drug availability at the tumor site while reducing harmful side effects. Nano-chemotherapeutics are able to accumulate at the tumor lesion due to the prolonged circulation of the nanocarrier and presence of abnormal leaky vasculature at the tumor site via the enhanced permeation and retention effect (EPR).
